To create the element, scientists bombarded a thin film of americium (atomic number 95) with calcium (atomic number 20) ions. The bombardment fused the nuclei of americium with that of calcium ...

The heaviest (i.e. highest atomic number) readily occurring element in nature is uranium, with 92 protons. Every element above it, including plutonium, americium, and einsteinium, can only be ...

ORNL actinides from HFIR (in parentheses) were involved in these superheavy element discoveries: flerovium-114 in 2000 (americium-243); moscovium-115 (americium-243), which was observed in 2004 ...

The UK's National Nuclear Laboratory and University of Leicester have generated usable electricity from the chemical element americium in what it believes to be a global first. The achievement is seen ...
